Telemetry represents the only technique currently available for data collection from unrestrained, freely moving mice.
Through the use of telemetry, it is possible to gather data continuously, for longer periods of time, from animals residing in their own familiar environment, thus minimizing stress to the animals and consequent experimental artifacts. Furthermore, in vivo studies from conscious, unanesthetized, instrumented animals are recommended by the FDA for ICH S7A studies.
The easyTEL system can simultaneously collect signals from implants, analog signals, biopotential electrodes and/or strain gauge transducers. This is particularly useful for neurorespiratory or cardiorespiratory applications. For example, pleural pressure from an implant and respiratory flow from a head-out plethysmograph can be simultaneously recorded, for precise resistance & compliance measurement.
